Eligibility
Inclusion criteria
Inclusion criteria: *recipients of hematopoietic stem-cell transplantation (HSCT) with graft versus host disease (GVHD) using PPI *start or use of posaconazole for invasive fungal infection (IFI) prophylaxis with concomitant PPI use for at least twelve days or one week when already using posaconazole
Exclusion criteria
Exclusion criteria: *current clinical significant invasive fungal infection requiring treatment *inability to sign informed consent *inability to take oral medication *allergy to posaconazole, PPI or the acidic beverage *start or discontinuation of a CYP3a4 inhibitor or P-glycoprotein inducer during the study period *age
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| difference in the bioavailability of posaconazole within patients on PPI with or without concomitant use of the acidic beverage in hematopoietic stem-cell transplantation patients with graft versus host disease. | — |
Secondary
| Measure | Time frame |
|---|---|
| To investigate whether the plasma concentrations of posaconazole in graft-versus-host-disease (GVHD) patients, adversely affected by the co-administration of proton pump inhibitors (PPIs), can be restored by the acidic beverage. Feasibility of concomitant administration of posaconazole and the acidic beverage in GVHD patients. Plasma pharmacokinetics of posaconazole at the start and at steady-state in graft-versus-host-disease (GVHD) patients concomitantly using PPI. | — |
